Shantou is a city, though not as developed as other Guangdong provincial cities such as Zhuhai/Guangzhou/Shenzhen. Shantou is basically the turf of the teochew people, where quite a number of ancestors of Singaporeans once hailed from. You'll find traditional stuffs like small mountains and temples as well as modern shopping malls/dingy shopping street over there.
Generally speaking, I like the food in Shantou.
Plan ahead, if you are bringing your family, recommend staying in the city centre, where it will be more convenient to charter transport to explore around. Be forewarned that Shantou is not as well developed as other modern cities. Facilities that may be adequate to the locals, may appear quite appalling to you.
Watch out for touts and cheats. Costs are DIRT CHEAP in Shantou. Don't pay more than you should for anything.
